Atomic Structure:
-Number of protons within the nucleus-17
-Number of electrons within the neutral atom-17
-Most common isotope- Chlorine-35
-Number of neutrons within the most common isotope- 18 neutrons
Background:
-Scientist Who Discovered the Element- Carl Wilhelm Scheele
-Year It Was Discovered- 1774
-Origin of the Name- Chlorine comes from the word "chloros", a Greek word, which means pale-green or greenish-yellow in reference to the color of the gas
-2 Most Common Uses- To purify water and swimming pools, and to combine with Na to make table salt
Physical Properties:
-State of Matter at Room Temperature- Gas
-Melting Point- -101.5 °C
-Boiling Point- -34.04 °C
-Density- 0.003214 g/cm^3
-Abundance in Earth's Crust- 0.017%
Chemical Properties:
-Other Elements That Will React with Your Element- Na to form table salt, H to form hydrochloric acid, it also reacts with iodine, fluorine, phosphorus, sulfur and many more. It does not react with nitrogen and oxygen under ordinary conditions though.
-Compound that Contain Chlorine- Oxide, hydride, chloride, chlorine fluoride, chlorine dioxide, and more.
-Chlorine is a very important factor in purifying our drinking water. It kills waterborne pathogens that can cause typhoid, cholera, and dysentary. Chlorine was added to water in 1908 and since then, many of these diseases have died down such as typhoid, which was once a huge problem, but is now almost nonexistent. Scientists think that chlorine, which is hypochlorite and hypochlorous acid in water, works with biomolecules in the bacterial cell to destroy it. A new theory is that chlorine destroys the cell wall, effectively destroying the bacteria. These are all theories, but we do know that chlorine is of vital importance in keeping our drinking waters safe and bacteria-free.
